Electromagnetic Induction (pHet simulation) is...
the use of the movement of magnets around a coil of wire to create an electrical current through the wire
the use of the movement of electricity around a coil of wire to create an electrical current through the wire
What conclusion can you draw from this graph?
As current increases, magnetic strength decreases.
As current increases, magnetic strength increases.
As current decreases, magnetic strength increases.
There is no relationship between current and magnetic strength.
Can you produce current in a wire with a magnet that is sitting still?
Yes; having a magnet near a wire is enough to excite the electrons
No; the magnetic field has to be changing to excite the electrons
No; magnets cannot create electricity
Which pairs of materials could be used to create electromagnetic induction?
Coiled wire, a magnet
Coiled wire, a battery
A magnet, a battery
None of the above
Why is magnetic induction important?
Electromagnets are very versatile
Every electric motor uses induction
Because it's an easy way to produce electricity
All of the above
What can electromagnets do that regular magnets can't?
Switch their magnetic fields
Explode
Be turned off
They are both the same in every way
